General Description

• The TMC8100-EVAL is an evaluation board for the TMC8100 universal encoder bus controller. Connecting the TMC8100-EVAL to the Landungsbruecke PC interface board gives access to the graphical user interface TMCL-IDE and its fast development tools.
• The TMC8100 acts as a peripheral interface block to deliver the extracted and adjusted encoder position information to the microcontroller or the motion controller over SPI or
• UART. This is achieved by the programmable high-performance serial communication engine for synchronous and asynchronous data.
• The TMC8100-EVAL supports both absolute and incremental encoders. The encoder interfaces are supplied by the external supply of the TMC8100-EVAL. The TMC8100 is provided with a 16MHz clock source and an EEPROM for application code storage.

Ordering Information

Quick Start
Required Equipment and Software

• TMC8100-EVAL-KIT
• USB-C cable
• Power supply (3V to 5.5V) and cables
• Motor with encoder (ABN/SSI/SPI/BiSS-C/EnDat 2.x/Other)
• PC with latest TMCL-IDE (Windows®)
• TMC8100 encoder interfaces example codes
• The latest TMCL-IDE and the user guide can be found on the website:
  www.analog.com/en/resources/evaluation-hardware-and-software/motor-motion- control-software/tmcl-ide.

Setup and Operation

• This TMC8100-EVAL should be used with the TMC8100 data sheet.
• The latest versions of the documents and the example code can be found on the website:
• www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/tmc8100evalkit

Figure 2. Example Setup: TMC8100-EVAL-KIT Connected to an ABN Encoder
To power up and set up the TMC8100-EVAL-KIT, a USB connection between the Landungsbruecke and the PC running the TMCL-IDE is needed. The software can be run without the external supply or the encoders attached.

•  To use the TMC8100-EVAL with an encoder, the TMC8100 must be flashed with code matching the encoder type. After connecting the encoder and providing an external supply, the TMC8100-EVAL is set for operation.

Software Tools

• On start-up, the TMCL-IDE automatically detects the board connected to the Landungsbruecke. The board name and all the board-specific tools available are displayed. The setting  can also be done manually from the ID1: Landungsbruecke in the Board Assignment tab.
• The General Settings is the main tool for the TMC8100-EVAL. The top section is used to program the TMC8100. The three tabs are separate subtools. 
• Figure 4. TMCL-IDE TMC8100-EVAL General Settings – Programming Section + Encoder Raw Values
• The Encoder Raw Values tool has dual functions. During setup, it provides feedback on the status, example, when TMC8100 is being flashed. Once set up, the tool can display the encoder position information in raw values. This function can be turned on and off by clicking Start Reading Encoder Data or Stop Reading Encoder Data, respectively.
• Figure 5. TMCL-IDE TMC8100-EVAL General Settings – Programming Section + Encoder Graph The Encoder Graph tool displays the encoder position information on a linear graph.
• Figure 6. TMCL-IDE TMC8100-EVAL General Settings – Programming Section + Circular Graph
• The Circular Graph tool gives a more intuitive representation of the encoder position and displays it on a circular graph (including live position). This tool requires the encoder resolution per rotation to be set.

Detailed Description of Software

• The data sheet includes a description of the TMC8100 architecture and functions. The software examples are on the product page.
  Detailed Description of Hardware

• TMC8100-EVAL-KIT Contents

• The TMC8100-EVAL contains the Landungsbruecke PC interface board, the Eselsbruecke bridge connection board, and the TMC8100-EVAL, fully assembled and tested. Prior to its first use, ensure that no damage occurred during shipment and any jumpers are properly installed. Follow best ESD practices while unpacking and handling the TMC8100-EVAL or any of its parts.

• TMC8100-EVAL Hardware

• The area around the TMC8100 marked by the black box represents the minimal circuitry needed for operation, including an external oscillator and an I2C EEPROM memory. Next to it, there are labelled test points for direct access to the programmable digital I/O pins.

• The incremental encoder is connected to the connector marked as INC ENC and the absolute encoder is connected to the connector marked as ABC ENC. The pinout of the cables must match the labelling on the board.

• The connector marked SUPPLY provides the supply to encoders. The polarity of the supply must match the labelling on the board, and the supply voltage must be kept within the board’s specified operating range of 3V to 5.5V.

• The TMC8100-EVAL provides access to the SPI and UART interfaces by headers. These allow to use the TMC8100-EVAL in standalone mode without the Landungsbruecke.

• The header, labelled VCCIO SELECTION, allows to select the TMC8100 supply using a jumper. When using the TMC8100-EVAL with the Landungsbruecke, the I/O supply must be set to 3.3V. In the standalone module, the I/O supply may be set equal to the external supply.

Bill of Materials

The encoder connectors and power mating connector are provided and already mounted on the TMC8100-EVAL board.
